The purpose of the WebContainer interval SMF record is
to record activity within a WebContainer running inside a WebSphere® Application Server for z/OS® transaction
server.
The web container acts as a web server handling HttpSessions
and Servlets. The EJB container is not aware of the purpose of the
WebContainer activity record and only records that the EJB has been
dispatched, but does not gather any of the detailed information, such
as HttpSessions, Servlets, and their respective performance data.
A single WebContainer record is created for each web container.
In
addition to data that is associated with an individual activity, there
are some cases of web container work that are performed outside the
scope of an individual request. For example, some instances of http
session finalization and http session invalidation are performed asynchronously.
In such a case a WebContainer interval record would record this data
WebContainer
SMF recording is activated and deactivated along with the activation
and deactivation of SMF recording for the J2EE container.
